Yes This is very related to BIAB. All the songs you love can be brought into BIAB and it will prepare the Chords for you.
About 5 yrs ago the Ext HD that had all my music (about 5000 songs) and synced to my iPod packed up.
Yesterday, I looked for a way to copy my iPod to my PC. After evaluating many Youtube videos, I thought this one was good.

Used it and Voila! I had all my songs on my PC. Worked perfectly. Per the video, I didn't copy the songs to my desktop. I copied them to my D drive where I have tons of space. BTW I have the iPod Classic.
